It really depends on the team in my opinion. Randy Caryle was always aggressive when pulling the goalie, he would pull him at 3 minutes and even if the team has a powerplay. The 2010-2011 Ducks team was amazing when down a goal and the goalie pulled, just ask Dallas fans that season but anyways it depends on if the coach believes the team can sustain that pressure. If he doesn't then keep the goalie in or pull him with less time. Its a judgement call, and I'm sure if any of us were coaches that we would fail at it, haha.
